Coprophagia in Dogs (Eating Their Poop) BLUE CROSS ANIMAL HOSPITAL 11051-97 Street Edmonton Alberta 780-424-0025 www.bluecrossvet.ca COPROPHAGIA IN DOGS (EATING THEIR POOP) Why do dogs eat stools? While most cases of coprophagia appear to be purely behavioral, there are indeed numerous medical problems that can cause or contribute to coprophagia. These problems must first be ruled out before a purely behavioral diagnosis can be made. What are some of the medical causes? Any medical problem that leads to a decrease in absorption of nutrients, causes gastrointestinal upset or causes an increase in the appeal of the dog’s stool, could lead to coprophagia. In addition to a complete physical examination, the puppy’s diet and its stool frequency and consistency should be evaluated. Stool testing for parasites would be the minimum level of testing. If the stool is unusually soft or appears to be poorly digested, additional stool or blood tests may be warranted. Feeding a poorly digestible diet, underfeeding, and medical conditions that decrease absorption such as digestive enzyme deficiencies or parasites, could lead to malnutrition, vitamin and mineral deficiencies and therefore an increased appetite and possibly stool eating. In addition, if the stools contain large amounts of undigested food material, there is an increased likelihood that the puppy would eat the stools. Another possibility is that grass eating is either an innate or learned response to gastrointestinal upset, which may induce vomiting or to act as a source of fiber. When adult dogs begin to eat stools, it may also be due to malabsorption of nutrients or nutritional deficiencies. In addition, any condition that might cause an increase in appetite or an unusual appetite, such as diabetes, Cushing’s disease, thyroid disease, or treatment with certain drugs such as steroids may lead to an increase in stool eating. Dogs that are placed on extreme calorie restricted or poorly balanced diets may also begin to eat their stools. It should also be noted that if a dog develops a taste for a particular dog’s stool, that dog should be tested for any type of condition that might lead to poor digestion of the food (and excess food elements remaining in the stool). What are some of the behavior reasons that a dog or cat might eat its own stools? Coprophagia is a common problem in some puppies, which usually clears up by adulthood. There have been many explanations suggested for this behavior. When left unsupervised, puppies may simply begin to investigate, play with, and even eat stools as a play, investigative or scavenging behavior. Since coprophagia may attract a great deal of owner attention, the behavior may be further reinforced. There may also be an observational component since the bitch cleans and ingests the puppy’s excrement in the nest, and puppies may learn to mimic the behavior of their mother or playmates who perform this behavior. The owner that uses the outmoded, inhumane and useless training technique of “sticking the dog’s nose” in its stool when it has soiled the home, may be further encouraging coprophagia. In adult dogs the innate behavior of grooming and cleaning newborn puppies and eating their excrement, along with the well documented fact that dogs tend to be attracted to sniff and lick infection or discharge of their pack-mates, may explain some of the motivation for coprophagia. Early intervention can help reduce the possibility that the behavior will become a long-term habit. Why do dogs eat the stools of other animals? This behavior is akin to scavenging. It is not unusual for dogs to steal food items, raid garbage cans, and chew on, or eat non-food items that most humans would consider unusual or even disgusting. Cat feces and those of some other animals often have enough appealing attributes (odor, texture, and taste), to overcome the fact that they are stools. Dogs that eat the feces of herbivores may be attracted to the digested vegetation. In fact, stools themselves are seldom unpleasant to dogs. It is one of the odors that they are constantly attracted to when investigating their environment. How can coprophagia be treated? Coprophagia can best be corrected by preventing access to stools, by thorough cleaning of the pet’s property, and by constant supervision when the pet is outdoors. At the first indication of stool sniffing or investigation the dog should be interrupted with a firm command, or a quick pull on the leash (this is particularly effective for dogs wearing head halters). If the dog is taught to come to the owners and sit for a special food treat immediately following each elimination, the new behavior may become a permanent habit. A remote citronella collar may be effective if the owner supervises the dog from a distance (or by watching through a window to the backyard) and immediately and consistently interrupts the dog every time it begins to mouth stools. Dogs with medical problems should be treated to try and correct the underlying cause. A change in diet to one that is more digestible, or one with different protein sources may be useful. Dogs on restricted calorie diets may do better on a high bulk or high fiber formula. The product Forbid can be used. It is a palatable powder placed on the food and when metabolized creates a bitter taste that is unpleasant when consumed in the stool.

Thalhotter/123RF “Poop is central to the story of how dogs came into our lives," write Duke University dog researchers Brian Hare and Vanessa Woods in their wonderful new book, Survival of the Friendliest: Understanding Our Origins and Rediscovering Our Common Humanity. I think they may be right. Molly, our beloved Labrador retriever, certainly loved to eat poop. Sometimes she would chow down on her own feces, and at other times, she preferred excrement of the cows that lived behind our house. Mary Jean and I found this practice (coprophagia) disgusting. We were not alone. Ben Hart and his colleagues at the University of California at Davis School of Veterinary Medicine surveyed nearly 3,000 dog owners about their pet’s penchant for poop.

  • Coprophagia” Is Defined As the Ingestion of Any Type of Faeces, and Is a Common Complaint of Dog Owners
    Homeward Bound Golden Retriever Rescue Golden Rule Training Canine Corprophagia "Coprophagia” is defined as the ingestion of any type of faeces, and is a common complaint of dog owners. For humans it can seem disgusting and embarrassing for our dogs to engage in this behavior. It is somewhat a natural act for dogs, but as we domesticate our pets, we expect these behaviors to disappear; however, they are still animals with natural instincts! A dog may eat its own faeces, those of another dog or the faeces of another species. Dogs commonly eat the faeces of cats with which they share a household (or farm animals). The only circumstance in which coprophagia is considered a normal behavior is when a mother dog eats the faeces of her pups from the time of their birth until about 3 weeks of age. It is felt that the mother does this to keep the area clean until the pups are able to move away from it to defecate. A clean area may be less likely to attract predators in the wild. What behaviors are linked with corprophagia? Coprophagia may be a behavioral or a medical problem. It may be a type of behavioral coping mechanism for an animal that is caught in a stressful situation, such as a sudden environmental change. It can also be a tactic to avoid punishment for having a bowel movement in an inappropriate area. Coprophagia can inadvertently be taught to a puppy or adult during housetraining; if the puppy or dog is scolded or he sees the owner 'cleaning up' the bowel movement in the house, the puppy may learn to 'hide' the bowel movement by eating it.

  • An Exploration Into the Psychotherapeutic Needs of Males Who Have Been
    An Exploration into The Psychotherapeutic Needs of Males Who Have Been Sexually Abused by Their Biological Mother in Australia: A Qualitative Description Study Lucetta Eva Thomas A thesis submitted for the degree of Doctor of Philosophy Faculty of Health The University of Canberra 2019 iii Abstract This thesis explores the experiences of males who have sought psychotherapeutic support for sexual abuse perpetrated by their biological mother in Australia, using a qualitative description research design. The research’s findings fill a gap in the existing body of sexual abuse knowledge, specifically regarding the requirements and needs of males who have been sexually abused by their mothers. The information in this thesis establishes recommendations for practitioners—whether sexual assault support workers, mental health nurses, relationship psychologists, medical doctors or psychiatrists—to use in an environment of limited resources for providing effective and appropriate support for maternally sexually abused males accessing their services. The sexual abuse experienced by these men when they were boys was often highly traumatic and, at times, extremely violent. The maternal sexual abuse has not only adversely affected their childhood, but their lives as adults. The research shines a light on gender stereotypes and myths of mothers as only gentle and caring nurturers and protectors of their children, and of males as only perpetrators of child sexual abuse. Important research outcomes include acknowledging the sexual abuse of boys by their biological mother and the therapeutic inclusion and comprehensive integration of this type of abuse into child abuse prevention—to protect boys from maternal sexual abuse in the future. vii Acknowledgements First, I acknowledge Greg, whose heartbreaking experience of abuse by his biological mother compelled me to undertake this necessary research.

  • Stop Your Dog from Eating Feces
    Stop Your Dog from Eating Feces Coprophagia is a nasty dog problem that dog owners hate. It does not make sense, as we feed them the best meals possible, and they chose to eat poop. Who figured? Eating feces issues are most common in puppies. However, it can be seen at any stage throughout a dog's life. For such a wide spread problem there hasn't been much research conducted into how to stop our dogs from eating poop. The good news is that there are many ways available to correct this nasty habit. Whichever method you try below, be consistent. You must enforce your strategy every time to be successful. This will soon be the new habit. So, why do dogs eat poop (dog or cat poop)? Let’s break them into two simple areas: 1. Behavioral – It’s either a habitual behavioral problem, or 2. Medical – There is an underlying medical issue. You can easily discount the medical issues by asking your vet to examine your dog. They have a battery of tests that will easily tell them if your dog has a deficiency that is causing them to need to eat feces. Keep your dog well vaccinated, as coprophagia will indeed cause other medical issues as expected from eating parasites resident in feces. Dogs eat their own poop because of the following reasons: - If a dog punished for defecating inside the house, he may on occasions eat his poop to "hide the evidence". - It tastes good to your dog - Sometimes anxiety causes them to do it – stress - Sometimes dogs develop this feces eating habit because they are copying the behavior of other dogs.

  • Fecal Microbial Transplantation and Its Expansion Into the Treatment of Other Diseases
    Fecal Microbial Transplantation and its Expansion into the Treatment of Other Diseases by Braden Thomas Millan A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science Department of Medicine University of Alberta ©Braden Thomas Millan, 2016 Abstract Background: Fecal Microbial Transplantation (FMT) has gained popularity due to its efficacy in the treatment of recurrent Clostridium difficile infection (RCDI). RCDI is associated with prolonged courses of antibiotics with high recurrence rates following the initial resolution of symptoms. The increased use of antibiotics in both healthcare and agriculture has led to increased prevalence of antibiotic-resistant microbes. Therefore, we first tested the hypothesis that patients with RCDI would harbor high numbers of antibiotic-resistant bacteria and secondly, that FMT would reduce the number of antibiotic-resistant gene containing bacteria. Furthermore, the association between microbial dysbiosis and inflammatory bowel disease (IBD) has enhanced interest in therapies targeting the microbiota. For RCDI, resolution of the infection using FMT correlates with efficient engraftment of the donor microbiota. The purpose of our mouse studies was to determine the efficiency of donor microbiota engraftment into the recipient following a short pre-FMT treatment regimen and investigate if this changed the FMTs ability to reduce the development of colitis in Interleukin-10 knockout (IL-10 -/-) mice. Methods: Using shotgun metagenomics, we sequenced the microbiota of 20 RCDI patients. The libraries from the RCDI patients and a healthy cohort (n=87) obtained from the Human Microbiome Project (HMP) were aligned against the NCBI bacterial taxonomy database and the Comprehensive Antibiotic Resistance Database (CARD).

So much so, in fact, that poop eating is often a reason people try to rehome a dog or even opt for euthanasia. While it is repulsive to human sensibilities, it’s not really all that bad from a canine point of view. Dogs evolved as scavengers, There’s a scientific name for this habit—coprophagia (kop-ruh- eating whatever they found on the ground or in the trash heap, fey-jee-uh)—and also both behavioral and physiologic reasons so their ideas of haute cuisine is somewhat different from ours. why some dogs view dung as a delicacy. In his Handbook of Applied Dog Behavior and Training, animal behaviorist Steven R. Lindsay says, that coprophagia “may be one of several appetitive survival behaviors that have evolved to cope with the periodic adversity of starvation.” In other words, when food is scarce, you can’t be picky.

  • Val Strong's Serotonin Enhancing Diet
    A Dog’s Dinner - Diet and Behaviour Val Strong MSc Introduction The way we manage what and how we feed our dogs can have a dramatic effect on their behaviour and mood, and it is only recently that more interest has been placed upon the effect of diet on the behaviour of our pet dogs. Many people never give a thought to what they are feeding their dogs. They can be influenced by a cute pet food commercial, or by Mrs Smith in the pet shop who must know what she is talking about because she sells the stuff! We are already aware that humans can alter their mental and emotional state by having a coffee, a cigarette, an alcoholic drink or by taking drugs (be they prescribed or recreational). Chemicals affect intellectual ability and mood, and food is made up of chemicals both natural and unnatural; if you doubt it, remember the effect that ‘E numbers’ have on children! So, are our dogs any different? The answer of course is no! In the past, little emphasis has been placed on how diet can affect canine behaviour, and it is interesting that in many specialist dog books, nutrition is only referred to within the context of clinical disease. It is, however, becoming increasingly obvious that those working in the field of animal behaviour and training must be familiar with the use of dietary manipulation in the treatment of certain behavioural problems, and it should form part of their behaviour modification toolkit. The Importance of a Balanced Diet Appropriate nutrition requires that all nutrients - carbohydrates, fats, proteins, minerals, vitamins and water - are consumed in adequate amounts and in correct proportions.

However, the structure and stability of microbiota are highly dependent on abiotic and biotic factors, especially in the gut, which can be colonized by transient bacteria depending on the host’s diet. We studied these impacts by manipulating the digestive microbiota of the detritivore Armadillidium vulgare and analyzing the consequences on its structure and function. Hosts were exposed to initial starvation and then were fed diets that varied the different components of lignocellulose.
